如何使用散景在熊猫数据框中为每组绘制一条线

Question

我将熊猫数据框分组为

                 registrationtime objecthandling  counts
0  2020-01-23 06:01:57.176000+00:00         Create       2
1  2020-01-23 06:01:57.176000+00:00         Delete       1
2  2020-01-23 06:01:57.176000+00:00   buildingUUID       1
3  2020-01-23 06:04:59.723000+00:00   buildingUUID       1
4  2020-01-23 06:07:37.707000+00:00   buildingUUID       1
5  2020-01-23 06:29:48.102000+00:00         Delete       2
6  2020-01-23 06:33:03.946000+00:00   buildingUUID       2
7  2020-01-23 06:34:15.447000+00:00   buildingUUID       1
8  2020-01-23 06:38:19.964000+00:00         Create       2
9  2020-01-23 06:38:19.964000+00:00         Delete       1
10 2020-01-23 06:41:17.589000+00:00         Create       1
11 2020-01-23 06:41:17.589000+00:00         Delete       2
12 2020-01-23 06:44:51.089000+00:00         Create       2
13 2020-01-23 06:44:51.089000+00:00         Delete       2
14 2020-01-23 06:44:51.089000+00:00       geometry       1

并且我想在Bokeh中绘制线条，其中x轴是datetime，因此列是[[registrationtime，而y轴是counts。但是，我需要根据<< objecthandling >>->列创建，删除，buildingUUID和几何图形的单独一行。在这种情况下，有四个不同的行到目前为止，我的代码

obj_handling_group = gdf.groupby(['registrationtime', 'objekthandling']).size().reset_index(name='counts')
source = ColumnDataSource(obj_handling_group)
p = figure(plot_height=350, plot_width=800, x_axis_type='datetime')
p.line(x='registrationtime', y='counts', source=source, color='navy')

显然，这给了我一行，但是我如何根据

objecthandling

列中的值来分离数据？

我将熊猫数据框分组为注册时间对象处理计数0 2020-01-23 06：01：57.176000 + 00：00创建2 1 2020-01-23 06：01：57.176000 + 00：00 ...
